This is amazing so far!
Just to start off, Ayumus's storyline was the most I've ever laughed while playing a mobile game, keep that stupid-in-a-good-way humor in, please! It's absolutely perfect!
The actual story is pretty good so far, I'm super interested how this will develop! Having two MC's on opposing sides of the story is a really nice and fresh concept, please explore that a lot and don't resolve it too quickly! (Or don't, whatever you like more. I'd rather have a lot of game material from awesome devs like you guys, than see you burn out along the way.)
The animations and models are also all *chef's kiss.* The only thing I noticed was some clipping in the very first sex scene with Tamiko (the cowgirl one). There's some black void around her genitals, probably from the leg being angled too far or something. But really, all of the remaining animations were great, you did a very nice job there, making it feel fluid.
The small, static pose-changes you did for the characters during dialogue also felt very organic and added a little more personality to them.
This is the first free game I'm seriously considering a donation for, I just want to see this finished too badly! If this quality keeps up on both characters, this could easily be my favorite Ren-Py game so far, you guys are great!
